How to Germinate Acacia Species Here’s a short guide on the general technique that Arkham’s Botanical uses to germinate Acacia seed. Best germination was obtained by nicking the seed (scarification) and although putting the seed in boiling water also increased germination, heating for longer than 3 minutes soon reduced success. Seeds from three widely differing provenances in Tasmania were tested to determine whether they had different responses to various dormancy-breaking treatments. Seeds Germinating seed.
